Was Phil Collins the Cadbury's gorilla?

No, Phil Collins was not the Cadbury's gorilla. The famous advertisement featured a gorilla playing the drums to his song "In the Air Tonight," but the gorilla was a trained actor in a costume, not Collins himself. The ad became iconic due to its unique concept and the association with Collins' music. Collins has expressed amusement at the ad, but he was not involved in its creation or performance.
